This is terribly myopic; you don't have to like FB or want to use it to recognize its influence. Consider the possibility that you just haven't really wrapped your head around it yet. Also, I'm gonna guess you don't know a whole lot of older people, and may be falling into the cognitive trap of thinking your experience of social demographics is reflective of the population at large.
You're guess is incorrect (I love that you have considered all the things I don't know whilst jumping to random conclusions). When I said: I don't really know anyone who uses it, I meant I don't know anyone under the age of 35 who uses the platform with regularity (remember, I said that it was dead, not that no-one used it...they have 3bn MAU, people use it but my point is that people don't use FB in the way that is often assumed by politicians...who btw, mainly see FB as a way to target voters...the political use of FB peaked with Obama).
